[en] Labour induction has become a common practice. Given the significant number of induced deliveries carried out each year, it is important to know the consequences of this induction policy. The effects of labour induction on the childbirth are still the subject of considerable controversy. The increase of the caesarean and instrumental extraction rates has already been emphasized in previous studies. This article is based on an analysis of 10,045 deliveries carried out in the CHR Obstetrical Clinic of La Citadelle, between 1991 and 1997. The conclusions are instructive. Thus a departmental policy of setting an induction level of 35% will allocate 2/3 of the workload between 8:00 AM and 8:00 PM during the week, with a preponderance on Friday. The Caesarean rate is not increased but peridurals and recourse to instrumental extraction are more frequent.
